Member Function Documentation

acquire()

void dw::framework::ManagedPortOutputBase::acquire

(

)

Acquire a buffer from the channel.

Note

only a single buffer may be acquired from channel at any given time. if the port is already holding a buffer this call is a no-op.

client should check after with isBufferAvailable() to know if buffer was actually acquired.

Exceptions

if	channel returns unexpected error.

bindChannel()

void dw::framework::ManagedPortOutputBase::bindChannel ( ChannelObject *  channel )

overridevirtual

Implements dw::framework::ManagedPortBase.

getAllBuffers()

dw::core::VectorFixed< GenericData > dw::framework::ManagedPortOutputBase::getAllBuffers

(

)

Returns

vector of all GenericData allocated in the channel memory pool.

getBufferGeneric()

GenericData dw::framework::ManagedPortOutputBase::getBufferGeneric ( )

protected

getMetadata()

ChannelMetadata & dw::framework::ManagedPortOutputBase::getMetadata

(

)

Get the metadata of the acquired buffer.

Returns

header of the acquired buffer

getProperties()

const Properties & dw::framework::ManagedPortOutputBase::getProperties ( ) const

noexcept

isBound()

bool dw::framework::ManagedPortOutputBase::isBound ( ) const

overridevirtualnoexcept

Implements dw::framework::ManagedPortBase.

isBufferAvailable()

bool dw::framework::ManagedPortOutputBase::isBufferAvailable ( ) const

noexcept

Returns

true if the Port is holding a buffer acquired from the channel.

reset()

void dw::framework::ManagedPortOutputBase::reset ( )

overridevirtual

Resets the packet sequence counter

Note

does not drop the bound channel.

Reimplemented from dw::framework::ManagedPortBase.

send()

void dw::framework::ManagedPortOutputBase::send

(

)

Send the buffer to downstream clients over the channel.

Note

if the Port has no acquired buffer this call is a no-op.

after this call the sent buffer will no longer be available. any pointers deduced from the previously held buffer should not be used.

Exceptions

if	channel returns unexpected errors.

sendAdvTimestamp()

void dw::framework::ManagedPortOutputBase::sendAdvTimestamp

(

)

Send an advance packet if a lockstep sync client is bound.

setCallbackBeforeSend()

void dw::framework::ManagedPortOutputBase::setCallbackBeforeSend

(

dw::core::Function< dwStatus()>

callback

)

Set callback function to be invoked before sending the data.
